As parents, we all want to protect and care for our children, and when they are younger it is generally acknowledged that parents have a right, and a responsibility, to do so. The law gives children more rights and responsibilities as they grow up, and when a child turns 16 they are effectively considered an adult and in many situations are deemed to be able to make decisions independently.
If however your child is unable to make decisions for themselves, perhaps due to a lifelong disability, catastrophic injury or declining health, an application can be made to the Court for someone to be appointed as Guardian.
